使用Raphael 画图(三) 事件 (javascript)

var butt1 = paper.set();
        var a1 = paper.circle(24.833, 26.917, 26.667).attr({fill: "#fff", opacity: 0});
        var a2 = paper.circle(24.833, 26.917, 26.667).attr({stroke: "black", fill: "#fff", "fill-opacity": .4, "stroke-width": 2}); 
        var a3 = paper.path("M12.582,9.551C3.251,16.237,0.921,29.021,7.08,38.564l-2.36,1.689l4.893,2.262l4.893,2.262l-0.568-5.36l-0.567-5.359l-2.365,1.694c-4.657-7.375-2.83-17.185,4.352-22.33c7.451-5.338,17.817-3.625,23.156,3.824c5.337,7.449,3.625,17.813-3.821,23.152l2.857,3.988c9.617-6.893,11.827-20.277,4.935-29.896C35.591,4.87,22.204,2.658,12.582,9.551z").attr({stroke: "none", fill: "#000"});
        butt1.push(a1,a2,a3);
